level warning lamp
With the key in steering lock position 2, the
warning lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, there is approx.
1.3 US qt (1,25 l) washer fluid remaining the reservoir.
The reservoir should be refilled with MB Windshield
Washer Concentrate “S” and water (or commercially
available premixed windshield washer solvent /
antifreeze, depending on ambient temperature, see
page 258) at the next opportunity. The reservoir for the
windshield and headlamp washer systems is located in
the engine compartment.
Note:
If the warning lamp comes on during subzero wether,
please check the concentration of the washer fluid in
the tank. If the concentration is not sufficient, the fluid
may have frozen. After the fluid in the tank thaws,
correct the concentration level. Brake pad wear indicator lamp
With the key in steering lock position 2, the
indicator lamp comes on and goes out when
the engine is running.
If the indicator lamp lights up during braking, this
indicates that the brake pads are worn down.
Have the brake system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.

Electrical outlet
Two electrical outlets can be found, one at the front
passenger footwell, and the other in the rear
compartment (always operational).To o p e n :
Flip up cover and insert electrical plug (cigar lighter
type).
Note:
The electrical outlets can be used to accommodate
accessories (e.g. air pump, auxiliary lamps) up to
maximum 180 W.
Stowing items in the vehicle
Wa r n i n g !
To help avoid personal injury during a collision or
sudden maneuver, always use partition net when
transporting cargo. Always fasten items being
carried as securely as possible using cargo tie-
down rings and fastening materials appropriate for
the weight and size of the load.

To o pen :
To unlock the hood, pull release lever (1) under the
driver’s side of the instrument panel. At the same time a
handle (2) will extend out of the radiator grill (it may be
necessary to lift the hood up slightly).
Caution!
To avoid damage to the windshield wipers or hood, open
the hood only with wipers in the parked position.Pull handle (2) to its stop out of radiator grill and open
hood (do not pull up on handle).
To c l o s e :
Lower hood and let it drop into lock from a height of
approximately 1 ft. (30 cm).
To avoid hood damage, please make sure that hood is
fully closed. If not, repeat closing procedure. Do not
push down on hood to attempt to fully close it.

Automatic transmission fluid level
The transmission has a permanent fill of automatic
transmission fluid.
Regular automatic transmission fluid level checks and
changes are not required. For this reason the dipstick is
omitted.
If you notice fluid leaks or gear shifting malfunctions,
have your authorized Mercedes-Benz Light Truck Center
check the transmission fluid level.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.Coolant level
To check the coolant level, the vehicle must be parked
on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the COLD LEVEL mark in
the reservoir.P20.30-0241-20

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase.Tire replacement
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 310.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 310.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

2. Loosen screw (2) using wrench supplied with
vehicle tools, see page 259. The screw (2) remains
in the holder.
3. Lift spare wheel carrier slightly and push lever (3)
to the right using screwdriver supplied with vehicle
tools, swing spare wheel carrier down and pull it out
from under the bumper.
4. Remove space-saver spare wheel.
5. Turn the bayonet lock clockwise to the endstop and
take off. Remove the cover and spare wheel.
Note:
Store bayonet lock and spare wheel cover in cargo area.

the take-up bracket so that it is always vertical
(plumb-line) as seen from the side, even if the
vehicle is parked on an incline.
7. Open jack further until jack arm end seats firmly in
the take-up bracket and its base sits squarely on the
ground. Jack up the vehicle until the wheel is clear
of the ground. Never start engine while vehicle is
raised.8. Unscrew and remove all wheel bolts. Keep bolt
threads protected from dirt and sand.
9. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.
Clean contact surfaces of wheel and wheel hub.
Install spare wheel on wheel hub. Insert wheel bolts
and tighten them slightly.
10. Lower vehicle to ground. Remove jack.
Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of jack see page 259.

Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18
°F (10
°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68
°F (+20
°C)
and ambient temperature = approximately +32
°F (0
°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.
